Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to contexta.cc, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote memory server that gives an AI assistant persistent, per-user memory with combined keyword, vector and graph search over notes, messages and documents.

What you can do: Search memory with keyword, vector and graph retrieval in one query
Read, create and update notes or documents by ID
Traverse the knowledge graph of typed entities such as people, projects, decisions and meetings
List, create and update tasks
List available workspaces
When to use it: Useful when you want an assistant to remember decisions, meetings and project context across sessions in Claude, ChatGPT or Cursor, or to keep a personal knowledge base that links people and projects without manual tagging.
Requirements: A remote MCP endpoint at mcp.contexta.cc over HTTP; a Contexta account signed in through OAuth 2.0 with dynamic client registration and PKCE, which the MCP client handles on first connection. No API keys or environment variables are needed.

Before you install

Your notes, messages and documents are stored on a third-party service and indexed into its knowledge graph. The assistant can create and update memories and tasks, so writes change stored data. Access is per-user via OAuth tokens that are refreshed automatically; review what you let it save.

Installation

In SourceWeft

Open Contexta in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cc.contexta%2Fcontexta-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Persistent memory & knowledge graph for your AI assistant.
Keyword + vector + graph search in a single lookup.

What is Contexta

Contexta is a memory MCP server that remembers like a human does — by meaning, by words, and by relationships.

Most memory tools give you one flavor of recall: embedding search, a raw log, or a graph you pay extra for. Contexta fuses all three into a single query. Your agent can ask "what did we decide about pricing with Acme last quarter?" and get back the right meeting, the right decision, and the people connected to it — in one round-trip.

Under the hood, Contexta indexes your notes, messages, and documents as typed entities (people, projects, decisions, meetings, tasks) and links them into a knowledge graph automatically. Every retrieval combines:

Keyword search — exact phrases, names, IDs
Vector search — semantic meaning across languages
Graph traversal — follow relationships between entities

Why Contexta

Typed entities out of the box — people, projects, decisions, meetings, tasks are first-class, not blobs of text
Knowledge graph included — no paid tier gate on the graph layer
Triple retrieval in one call — no need to stitch together three different memory APIs
30-second setup — install via Smithery, sign in with OAuth, done
Per-user OAuth — your memory is private; the server authenticates every request individually
Multilingual — English and Russian equally supported

Use cases

Persistent memory for Claude, ChatGPT, and Cursor across sessions
Long-term context for AI agents working on ongoing projects
Personal knowledge base that actually understands who and what you mean
Research and meeting recall without manually tagging anything

Install

Via Smithery (recommended)

One-click install from the Smithery listing — Smithery handles the OAuth flow and proxies connections through its gateway.

Manual — Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

Claude will walk you through the OAuth sign-in on first use. See examples/claude-desktop.json.

Manual — Cursor

Add a new MCP server in Cursor → Settings → MCP:

Name: Contexta
Transport: HTTP
URL: https://mcp.contexta.cc/mcp

See examples/cursor.json.

Manual — ChatGPT

In ChatGPT → Settings → Connectors → Add custom connector → paste https://mcp.contexta.cc/mcp. See examples/chatgpt.md for full instructions.

Authentication

Contexta uses OAuth 2.0 with dynamic client registration (RFC 7591) and PKCE. On first connection, your MCP client opens a browser window, you sign in with your Contexta account, and the client receives a per-user access token. Tokens are refreshed automatically.

No API keys, no shared credentials — every request runs as a specific user with that user's private memory.

Tools exposed

Contexta MCP exposes the following tools to your AI client (non-exhaustive):

search — keyword + vector + graph search across your memory
read_page — fetch a note or document by ID
create_page — save a new memory
update_page — edit an existing memory
graph_search — traverse the knowledge graph
list_tasks / create_task / update_task — task management
list_workspaces — available workspaces
and more — the full tool list is discovered automatically by your MCP client.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
